Fisher Company, Inc. Consulting Engineers ^"<;r,# a vforreoa 3aem \i , < FOREWORD Staging Plan of Removal or Abandonment of Existing Utility Lines to Clear Parcels Within the Project Area The following report is based upon data and schedules received from private utility companies, utility consultants for the City of Boston, the Boston Redevelopment Authority and the Metropolitan Transit Authority. Much of the data is so con- clusive that definite abandonment dates may be determined. However, many utilities are dependent on a prior action by other agencies before final abandonment can be accomplished. It is evident that future decisions and approval of proposed work by the Boston Redevelopment Authority and the City of Boston will be required to initiate final approval of individual utility abandonments. -1- A1 This report will stage each parcel with its included utilities. It will be seen that many utility abandonments are dependent on action by the City of Boston or the Boston Redevelop- ment Authority. A definite staging date can only be accomplished on several parcels when these authorities can act on the following: demolition of buildings, the closing of existing streets, and the approval of new streets for the construction of proposed utilities. PARCEL 1 STATE COMPLEX The construction date for this parcel is understood to be March 1964. A review of the following utility problems will show that demolition of buildings is a vital issue for clearance. In particular, a five-foot strip inside the present north Cam- bridge sSt. property line is needed by the N. £. Telephone & Tele- graph Co. for proposed duct construction. The Boston Edison Co. needs a thirty-day period after the existing streets are closed to remove their existing conduits. Disposition of the Langone property is an urgent problem for total parcel clearance. The following is a resume of data indicating proposed abandonment of existing utilities. Boston Gas Co . Pipe lines have been abandoned on Hale St. and Norman St. Pitts St. is partially abandoned from Merrimac St. to a point approximately midway between Pitts Court and a private way. Aban- donment of lines for the remainder of Pitts St. is subject to the demolition of building 4 and 5, block 126A on Pitts St. Abandon- ment of lines for Green St. is subject to the Pitts St. clearance and the demolition of Building 1, Block #147. Norman St. lines are abandoned with the exception of a short piece of supply and service coming from Staniford St. and ending about midway of Building 1, Block Û24A. Norman St. can be cleared when the school building is demolished. The pipe in Chardon St, between Merrimac St. and Bowker St. will be abandoned subject to relocation in New Chardon St. N. E. Telephone & Telegraph Co .
